the increased use of timber both in the substructure and superstructure, as well as potentially retaining and reusing existing foundations where appropriate. The report also looks at the interactions between low carbon design, construction solutions and climate change resilience. And, to help illustrate the issues and solutions covered, case studies are included throughout.

space for future growth of roots, stems and canopies to maturity, mitigating risk of direct contact to structures, causing obstruction of access, light or nuisance – as noted in BS 5837:2012 the aim should be to “achieve a harmonious relationship between trees and structures that can be sustained in the long term.”


REDUCING THE CARBON FOOTPRINT he fi rst step in being able to reduce the carbon footprint of foundation systems is to recognise that foundations represent a substantial component of carbon


emissions relating to construction and can therefore make a signifi cant impact in the drive towards net zero. The Building Foundation Solutions report examines the range of low carbon foundation solutions that are currently available, including the use of lower carbon cement products or alternatives to cement that could result in a carbon reduction of up to 50% compared to standard concrete. Reducing carbon within foundations can be achieved in a variety of other ways, including using odern ethods of onstruction ,
